APPARATUS FOR DELINTING COTTON-SEED.

SPECIFICATION forming part of Letters Patent No. 458,833, datedSeptember 1, 1891.

Application filed April 17, 1891. Serial No. 389,335. (No model.)

To aZZ whom it may concern: 7

Be it known that we, JOSEPH HoLLINos- WORTH and OvERToN DARWIN, bothresidents of Waco, in the county of McLennan and State of Texas, haveinvented certain new and useful Improvements in Apparatus for DelintingCotton-Seed; and We do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

Our invention relates to improvements in apparatus for burning off orremoving the lint from cottonseed.

The invention consists in the novel construction and combination ofparts hereinafter fully described, and specifically pointed out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of anapparatus constructed in accordance with our invention. Fig. 2 is acentral vertical section of the same.

In the said drawings the frame of the apparatus is shown as consistingof the uprights 1, inclined bars 2, side bars 3, and cross-bars i and 5.These parts may be made of any suitable material bolted or otherwisesecured together.

The numeral 6 denotes a metallic sprocketroller having short journals 7,which work in bearings in the side pieces 2. At the upper part of theframe there is a similar roller 8, which is also provided with journals9, which work in bearings in said frame. Passing over these rollers isan elevator consisting of sprocket-chains 11 and buckets 11, so arrangedthat as the rollers are revolved by any suitable means the elevator willbe actuated. As will be seen, the elevator occupies a diagonal position.

At the lower or under side of the elevator and parallel therewith is ahot-air flue 10, the lower end of the inner wall of which is curved andextended around the roller 6 and secured to the front cross-bar 4. I Theupper end of the fiue is supported by crossbar 5.

Located at the rear of the frame, at the lower part thereof, is afurnace 12, having a grate 13, which is secured to the side pieces 3 andrear cross-bar 5. The flue just above the fur nace is made flaring, soas to fit over the same and form part thereof, its side being providedwith doors for the insertion of fuel.

A hood 14 is placed over the upper side of the elevator, completelyinclosing the same and forming with the inner wall of the flue a hot airchamber. The lower part of this hood is secured to the crossbar 4 and atits front lower edge is provided with an opening for feeding anddischarging the seed. Extending centrally across this opening is a shaft15, j-ournaled in the inclined bars 2 and having two wings 15 and 15 setat an angle to each other, forming a double door. This shaft may beprovided with a suitable operatinghandle. \Vhen the lower wing of thedouble door is closed, the upper one is open, so that the apparatus ischarged, and when the upper wing is closed the lower one is open,allowing the grain to be discharged.

The operation will be readily understood. A fire is started in thefurnace and the apparatus is charged through the opening in the lowerpart of the hood, the upper door or wing being opened for that purpose.The elevator is then actuated and the buckets thereof will catch theseed and carry it upward and then down 'over the inside or back of theflue and is discharged through the lower part of the opening in thehood, the lower wing being opened for that purpose. In its passagethrough the apparatus the lint is burned off.

All the parts of the apparatus are to be made of metal, and an inclinedtrough 16 is located below the discharge-opening to re ceive the seed asit comes from the elevator.

lVe prefer to form the inner wall of the hotair fiue of wire-cloth orperforated metal, so that the hot air can readily enter the hot-airchamber.

Having thus described our invention, what we claim is 1. Thecombination, with the frame, of the inclined hood supported thereby,having an opening for introducing the seed and an opening fordischarging the same near its lower end, the elevator consisting of theendless belt and the sprocketrollers journaled in said hood, the furnacelocated in the lower part of the frame, and the flue communicating withsaid furnace, substantially as described.

2. The combination, with the hood having an opening near its lower end,of the double door extendingaoross said opening, comprising two Wings atan angle to each other hinged or pivoted to said hood, substantially asdescribed.

In testimony that we claim the foregoing as IO our own We have hereuntoaffixed our signatures in presence of two Witnesses.
